Hockney Repeats at Tate Britain

I've seen the David Hockney room at Tate Britain a few times and thought that his three huge landscape paintings (made up of lots of smaller paintings) which all looked very similar were a bit rubbish - although I quite liked the repetition. It was pointed out to me yesterday on a flying visit that only one of the paintings is actually a painting and the other two are photographs of the original. This makes it all quite a lot more intriguing and interesting. It also means that I obviously do not look at things properly.

I can't find a picture of the room to post here (the Tate website does not have an image - maybe there are copyright issues) only an image of the painting which is called Bigger Trees Near Warter Or/Ou Peinture Sur Le Motif Pour Le Nouvel Age Post-Photographique, 2007
